The present disclosure relates to an optical image capturing lenssystem, and more particularly, to a compact optical image capturing lenssystem used in electronic products.

2. Description of the Related Art

The demand for compact imaging lens assembly has grown in recent yearsas the popularity of portable electronic products with the photographingfunction has increased. The sensor of a general photographing camera isnone other than CCD (Charge Coupled Device) or CMOS (Complementary MetalOxide Semiconductor) sensor. Furthermore, as the advanced semiconductormanufacturing technology has allowed the pixel size of sensors to bereduced, and the current electronic products are leaning toward a trendof being more compact, there is an increasing demand for higher imagequality.

A conventional compact imaging lens system with high image qualityequipped on a portable electronic product is often composed of four lenselements such as the lens system set forth in U.S. Pat. No. 8,179,470.However, with the popularity of high level portable electronic products,such as smart phone and PDA (Personal Digital Assistant), the demand forthe pixel size and image quality of compact imaging lens system increasefast, and the conventional lens system with four lens elements can nolonger satisfy the imaging lens systems of even higher level. Althoughlens systems adopting five lens elements begin to emerge recently, suchas the lens system set forth in U.S. Pat. No. 8,000,030, the lens systemstruggles in handling the off-axis incident-light so that it tends tohave a vignetting effect in the formed image and the relativeillumination of the lens system is so low that the image quality becomesundesirable.

In light of the foregoing, an optical image capturing lens system thatis suitable for portable electronic devices and has excellent imagequality is in need; especially for those whose fifth lens element isconfigured with stronger positive reflective power, which is favorablefor positioning the principle point away toward the image plane. Thus,the angle of incidence from the off-axis field can be effectivelycontrolled for improving relative illumination of peripheral Image andpreventing the occurrence of vignetting, which are favorable forimproving image quality.

A front stop can providea longer distance between an exit pupil of the system and an imageplane, and the image-sensing efficiency of an image sensor can beimproved. A middle stop is favorable for enlarging the field of view ofthe system and thereby provides a wider field of view for the same.

According to the optical image capturing lens system of the presentdisclosure, each of an object-side surface and an image-side surface ofevery lens element has a paraxial region and a peripheral region. Theparaxial region refers to the region of the surface where light raystravel close to an optical axis and the peripheral region refers to theregion of the surface where light rays travel away from the opticalaxis. Particularly, when a lens element has a convex surface, itindicates that the surface is convex at the paraxial region and when thelens element has a concave surface, it indicates that the surface isconcave at the paraxial region.

A critical point is referred as a tangential point on a surface of thelens element concerned where the corresponding tangent through thecritical point is perpendicular to the optical axis. Please refer toFIG. 11. A vertical distance with respect to the optical axis 1101between a critical point 1102 on the object-side surface 1151 of thefifth lens element 1150 and the optical axis 1101 is Yc51; wherein thecritical point 1102 is not on the optical axis 1101.

The present optical image capturing lens system can be optionallyapplied to MEMS (Micro-Electro-Mechanical System) focusing and zoomoptical systems. In addition, as the optical image capturing lens systemhas the advantages of superior aberration correction ability and finerimage quality, it is suitable for applications in imaging systems suchas 3D (3 dimensional) image capturing, digital cameras, portabledevices, digital tablets and etc.
